[PATCH v3 03/12] target/arm: Use set/clear_helper_retaddr in SVE and SME helpers

Avoid a race condition with munmap in another thread. Use around blocks that exclusively use "host_fn". Keep the blocks as small as possible, but without setting and clearing for every operation on one page. Signed-off-by: Richard Henderson --- target/arm/tcg/sme_helper.c | 16 ++ ta
